It consists of a main body lead which is swingably attached to the main body 49 by a pivot member π, and an advancing/retracting rod ω protruding from the main body 49, and the advancing/retracting rod ω is always biased in the direction of extension from the main body 49 (the main body 49 (by means of a biasing means such as a spring or compressed gas), and is configured to move slowly in that direction (similar configuration to a well-known shock absorber). Further, the advancing/retracting rod ω is configured to quickly move in the direction of recessing into the main body a (movement in the direction of resisting the biasing force). Reference numeral 51 denotes a connecting device that connects one piece of the lever chrysanthemum to the tip of the advancing and retracting lever, and as shown in Figure 6, it is constructed so that its position can be changed within the range of the long hole provided in the lever chestnut. By adjusting its position, the magnitude of the biasing force (in multiple clockwise directions in FIG. 4) that the biasing device applies to the lever chrysanthemum can be adjusted. The connecting device 51 is composed of a connecting member & and an adjusting screw ω, and the connecting member & includes a connecting member, a shaft member 56 protruding from both sides of the connecting member, and a portion near the tip of the shaft member 56. Between the threaded parts a, 5

The above pins are moving body A, 37, cylindrical body A, and washers 3g a and 3g b.

39C and the hole Ua formed in the arm H, and is prevented from being removed by tightening portions 4oa and 40b at both ends of the pin chrysanthemum. The length of the elongated hole 47 is the length of the arm ■
The length is such that the connecting member attached to the arm H can move within the elongated hole 47 over the entire range of movement as will be described later.

Next, a movement limiter is attached between the arm U and the base frame 2 to restrict movement of the arm 11.

This movement restriction mechanism consists of a movable body a, exemplified as a retainer attached to the middle part of arm U, and a guide hole system, exemplified as a guide path formed in base frame 2 to guide this movable body. It consists of

As shown in FIG. 8, the guide hole U is a first circular arc whose center is at the forward end position of the connecting body in the elongated hole 9 and whose radius is the distance m between the moving body and the connecting body U. Guide hole 6
Then, the support body 4 is closed inside 11>, and a second guide hole having a circular arc shape whose radius is the distance n between the movable body W at the forward end position B and the support body C in the first guide hole δ is formed. It is configured. Note that the second guide hole does not necessarily need to be formed in an arc shape centered on the support body C, but it may be formed so that the second guide hole and the long hole 47 of the lever box intersect.
It is preferable to always restrict the movement of the elongated hole 47 and the second guide hole. Further, the arm H may be provided with a pin as an engaging body separately from the connecting member portion, and the base frame 2 may be provided with a guide groove as a guide path, and the pin may be guided by this guide groove. The length of the first and second guide holes δ and 26 is the arm U.
The connecting member 5 is formed in a size that does not hinder the movement of the connecting member 5 over the entire range of movement as will be described later.

The arms 1, 12, the movement limiting mechanism, the biasing mechanism 41, etc. are provided on the base frame 2 on the left side and the base frame 2 on the right side, respectively, with the frame body 5 as the center. In Figures 2 to 6, the one installed on the right side is shown, but the one installed on the left side is just the right and left side when viewed from the direction of Figure 2. Since the configurations are exactly the same, detailed explanation thereof will be omitted. The problem is that the cover must be attached to the base frame 2 to cover the biasing mechanism d.

In the case of the above structure, when the frame body 5 is to be pulled down toward the user, the handle 8 is grasped and the handle 8 is pulled forward and downward against the biasing force of the biasing mechanism. Then, in the first half of the movement of the frame 5, as shown in FIGS. 3 to 7, the arms 1 and 12 move forward centering on the connecting bodies 13 and 14 at the forward end positions of the elongated holes 9 and 10. tilt. In this case, the movable body d attached to the arm H is connected to the first guide hole δ in the shape of an arc centered on the connecting body at the forward end position A of the elongated hole 9.
Since its movement is restricted to move within the arm 1
The connecting body 13 at the lower end is held at the forward end position A of the elongated hole 9. Furthermore, the connecting body opening and the connecting body 14 are connected to a connecting piece 15.
Since the connecting body 14 at the lower end of the arm is also held at the forward end position of the elongated hole IO. Therefore, the frame body 5 is moved approximately horizontally forward by the two roughly parallel arms u and 12 on both sides, and is positioned in front between the two claw frames 2. In the above case, since the connecting member is fitted into the elongated hole 47 of the lever shaft in the biasing mechanism 41, when the arm 11 is tilted forward as described above, the moving body of the connecting member moves in length. While moving the inside of the hole 47 toward the distal end, the lever shaft is rotated clockwise in FIG. 8 around the support rim, and the forward and backward movement of the biasing device is pushed in the retracting direction. After that, when the handle 8 is further pulled forward and downward, the arms (2) and 12 are tilted further forward, but in this case, the movable body W attached to the arm H has an arc shape centered on the support C. Since the movement of the movable body is restricted so that it moves inside the second guide hole, the movable body is forcibly moved downward within the second guide hole. Therefore, the connecting body 14 at the lower end of the arm 1 is moved rearward within the elongated hole 9 as the arm J1 is tilted forward, and the connecting body 14 at the lower end of the arm is also moved rearward within the elongated hole 10. . In this way, in the process of the arms 1 and 12 tilting forward, the connecting body opening,
14 moves rearward as described above, the frame 5
From the position shown in the figure, it does not move forward very much, but mainly moves downward, and is in the lifted state as shown in FIG. In addition, when the arms 1 and 12 are tilted forward as described above, the connecting member A is biased upward by the biasing mechanism at the beginning, but the direction of the biasing force is reversed near the end. Thereafter, the connecting member portion is urged downward as shown in FIG. Therefore, the arms 1 and 12 are stably held in the tilted position in which the movable body a of the connecting member abuts against the lower end of the second guide hole. In addition,
In the above case, at least one of the connecting bodies 13 and 14 is connected to the elongated holes 9 and 1 before the movable body comes into contact with the lower end of the second guide hole.
The lowermost position of the frame 5 may be determined by contacting the rear end of the frame 5.

Next, when storing the frame 5 in its original position, the frame 5 is pushed upward from the state shown in FIG.

At this time, after the frame body 5 is slightly lifted, the biasing force of the biasing mechanism comes to work in the direction of pushing the arm (2) upward, so that the above-mentioned pushing up can be performed with a light force. In this process of pushing up, the linking member is moved inside the second guide hole can as in the case of pulling down, so the arm 1
1 and 12 are connected bodies.

The connecting body rotates upward about 14, and
14 is moved forward, and the frame 5 is thereby moved upward. After the frame 5 is raised as shown in FIG. 7, the connecting member portion is guided to the first guide hole, so the arms 11 and 12 are connected to the connecting member at the forward end position of the elongated holes 9 and 10. 13 and 14, and thereby the frame body 5 is moved approximately horizontally rearward and stored in its original position between the base frames 2. In this stored state of the frame 5,
Since the movable body W of the connecting member portion is urged backward (by the urging mechanism 41) and abuts against the rear end of the first guide hole 6, the frame body 5 is stably held in the storage position. .

Next, FIGS. 9 to 17 show different embodiments of the biasing mechanism and the movement limiting mechanism. As shown in FIGS. 9 to 11, the biasing mechanism 41e in this embodiment is provided with a frame 5elllllK on the base frame 2e. The linking member 35e of the biasing mechanism 41e is composed of a moving body 33e, a bottle @e, and a washer 39ce. The moving body 36e
The shaft portion 36ae is movably fitted into the elongated hole 47e,
The pin 40e is connected to the hole 11ae of the arm 11e and the movable body 36e.
and the rear tightening portion 411ae, 4 inserted into the washer 3988.
Extraction is stopped by 0be.

Next, the movement limiting mechanism 23e is shown in FIGS. 9, 12, and 18.
As shown in the figure, there is a pivot body (material) attached to the base frame 2e, a retaining lever 81 whose base part is rotatably attached to the pivot body, and a ninth In the figure, a biasing means 82 (a coil spring is used as an example, but other structures may also be used) biases the engagement lever 81 in the counterclockwise direction, and the rotation of the engagement lever 81 by the coil spring 82 is provided. A receiving pin 83 and one end 81 of the retaining lever 81
& the other end 8 of the engagement lever 81
1b and a connecting piece 85 that connects the connecting body 13e at the lower end of the arm 116. The pivot body (material) is composed of a pivot port 86 and a nut 87. This pivot port 86 includes a pivot portion 86a, a fitting portion 86b, and a threaded portion 86.
The fitting part 86b is rotatably fitted into a hole 88 formed in the base part 2e, and is prevented from being removed by a nut 87 screwed into a threaded part 86el. .

A spring insertion hole 89 is formed through the pivot portion 86&. The engagement lever 81 is formed into an L-shape with two free ends, and a hole 90 formed in its base (middle part) is integrally fitted into the pivot portion 86B. The coiled spring 82 is located on the outer periphery of the pivot portion 86&,
Its inner end is inserted into the spring insertion hole 89 and connected integrally, and its outer end is connected to a pin 91 fixed to the base frame 2e.
The pivot shaft and the retaining lever 81 are connected to each other to bias the pivot shaft and the retaining lever 81 in one direction. The receiving pin blade is the other end 8 of the engagement lever 81.
1b is positioned so as to receive rotation of the engagement lever 81 at a position facing substantially forward. Note that the receiving pin 83 may be omitted by bringing the connecting body 13e into contact with the front end of the elongated hole 9e to prevent rotation of the engagement lever δ1. As shown in FIG. 16, the engaging body cavity is opened when the arm 1
1e. This retention body temperature is made up of a support shaft 92 fixed to the retention lever 81, a roller 93 rotatably attached to the support shaft 92, and two washers 94&, 94b. An annular groove 95 is formed which engages the arm lle. One end of the connecting piece 85 is connected to the other end 81 of the engagement lever 81.
b by a connecting pin 96, and a hole 85a provided at the other end is rotatably fitted into a shaft 19e of the connecting body 13e. This connecting body 13e is a moving body 17e
and a cylinder body 97 and washers 98a, 98 outside the shaft body 19e.
It also has b.

In the structure described above, until the frame 5e is pulled forward between the base frame 2e as shown in FIG.
4e are elongated holes 9e and 10e due to the spring force of the coiled spring 82.
When the arm 11e is positioned at the forward end position and then tilts forward by pulling down the frame 5e,
As shown in FIG. 15, the arm 11e engages with the roller 93 of the engaging body cavity to rotate the retaining lever 81 clockwise in FIG.

As a result, the connecting piece 85 moves the connecting body 13e rearward to the state shown in FIG. 17.

Next, when the frame 5e is pushed upward from the state shown in Fig. 17,
As the arm 11e rotates upward, the engagement lever 81
is rotated counterclockwise in FIG. 15 by the spring force of the coiled spring 82, thereby
6 is moved forward to the state shown in FIG. after that,
The arms 11e and L2e are swung rearward by the urging mechanism 41eK, and the frame 5e is stored in its original position as shown in FIG.

It should be noted that parts that are considered to have the same or equivalent structure as those in the previous figure in terms of function are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted. (Also, in the following items, the alphabet f is added based on the same idea and redundant explanations are omitted.) Next, FIGS. 18 and 19 show another different embodiment of the movement restriction mechanism. The other end 81b of the engagement lever 81f
By forming a fitting recess 99 in f, the coiled spring 8
Forming a hook piece 100 projecting in the direction of rotation by 2f,
The hooking piece 100 of the engaging lever 81f is hooked on the receiving pin 83f when the engaging lever 81f is in contact with the receiving pin 83f. With this structure, a connecting piece is attached to one end 81bf of the engaging lever 81f. 18th by 85f
Even when a large tensile force is applied to the left in the figure, the tensile force is received by the engagement between the hook piece 100 and the receiving pin 83f, and the large tensile force is prevented from being applied to the pivot body f. It is possible to prevent damage to the pivot body sof.

In the case of the above configuration, when the arm 11f rotates forward and comes into contact with the engaging body 84f, the hooking piece 100 is first removed from the receiving pin 33f by a slight tilting of the lever 81f, and then the hooking piece 100 is removed from the receiving pin 33f, and the process continues as in the previous embodiment. Similar movements are performed.

Next, to show another different aspect of the above configuration, in order to make the lower end of the arm movable back and forth, the elongated hole 9.
10 and the mobile body 14, the following configuration may be used. That is, in the base frame 2 in the front-rear direction (the elongated hole 9.1
Attach two rails pointing in the same direction as 0), equip these rails with large pieces so that they can move back and forth along each rail, and place the lower ends of each arm on those pieces in the same direction as above. It may be pivoted to allow tilting.

As described above, in this invention, (a) Even if the frame 5 is arranged at a high place that is out of reach, when taking out an article from there, the frame 5 can be moved to a low place. It is possible to move the articles stored there and handle them from a low position, which has the effect of making it easier to take out the articles.

(b) Moreover, in the first half of the movement of the frame 5 as described above, the frame 5 can be largely moved substantially horizontally forward while the pivot point of the arm is held at the forward position. This has a great effect in that even if the frame body 5 has a large depth, it can be taken out as described above.

(C) Furthermore, even if the arm is used to descend as described above using its lower end as a pivot point, the downward trajectory of the frame 5 will return to the original trajectory in the process of descending following the first half. # (trajectory # of the frame 5 descending while the pivot point of the arm remains at the front) is a trajectory where the frame body 5 is lowered backwards, so the forward movement of the frame body 5 in the above process is It has the advantage of being able to reduce the protrusion dimension. This has the practical effect of making it possible to use the vehicle not only in places with a wide front space, but also in narrow places.
